Yes, it's safe to delete. It is the backup of the file that
BounceRunner was processing when something happened, and BounceRunner
never 'finished' processing the file.  There was a hole that allowed
this to occur on an 'unparseable' (almost always spam) message in
2.1.9, no whenever you get the "Ignoring unparseable message" in the
error log, the .bak file is left behind. This is fixed in 2.1.10n now
in beta.

Apparently, 3252 was the pid of BounceRunner on Jan 2 (from the .bak
above and the Jan 2 log message. The Jan 24 log message seems to be a
retry of the 'recovered' .bak file implying BounceRunner was
restarted. If BounceRunner dies in some ways, it can leave the
bounce-events file behind. If it restarts with a new pid, the old file
is orphaned and can safely be deleted.

Actually any bounce-events file can be deleted. The worst that will
happen is you'll lose a few bounce events.

Yes, it's safe.
